1930. Serial No. 448,060

2 Claims. (01. 110-92) This invention relates to improvements in smoke consumers and has for its primary object the provision of an improved construction and arrangement of this character, adapted and arranged to induce complete combustion and thereby prevent the escape or emission of smoke from boiler furnaces and the like.

Another object of the invention is the provision of an arrangement of the character indicated, equipped with means facilitating cleaning thereof.

Another object of the invention is an arrangement of the character indicated especially adapted for use in conjunction with tubular boiler furnaces.

Other objects will appear hereinafter.

The invention consists in the combinations and arrangements of parts hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawing forming a part of this specification, and in which Fig. l is a partial vertical longitudinal section of a boiler furnace equipped with a smoke consuming means embodying the invention.

Fig. 2, a partial section taken substantially on line 2-2 of Fig. 1.

In the'embodiment of the invention illustrated in the drawing, an ordinary tubular boiler furnace 18, provided with the usual boiler tubes 19, is provided at its front end with a distributing chamber 20 arranged over the entry ends of the boiler tubes and having an upper passageway 21 communicating with the uppermost central boiler tube 19, as shown. The distributing chamber 20 is provided at its lower end with a forwardly extending entirely across the bottom thereof. A forwardly extending heating chamber 29 is removably attached to the lower forward side of the distributing chamber and communicates freely with the lower portion thereof. Arranged within the heating chamber 29 is a medial horizontal partition 30 having upwardly and downwardly extending connected fins or partitions 31 which subdivide the chamer 29 into a plurality of tortuous passage-ways for the products of combustion as will be readily understood. The forward portions of the fins or partitions 31 are provided with registering openings 32 and a tubular entry 33 is provided for one side of the heating chamber 29, said entry being closed by an external threaded plug 34:, as shown in Fig. 4. By this arrangement, the products of combustion passing to the boiler tubes 19 will be intensely heated as before. When it chamber, said flattened is desired to clean the tortuous passage-ways, a hose nozzle may be inserted through the passage-way 33 and compressed air blown through said passage-ways for the purpose.

While I have illustrated and described the pre- 0 ferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

I claim:

1. In a furnace, a grate, a combustion chamber above the grate, a horizontal fire tube boiler having the inlet ends of the tubes communicating with the upper rear portion of the combustion chamber, means enclosing the inlet ends of the tubes and forming a distributing chamber, said" means having an elongated inlet opening at its lower forward end co-extensive with the width of the boiler, a flattened elongated casing extending forwardly parallel to the grate from said distributing chamber, said-flattened casing being 0 closed at its forward end and communicating at its rear end with said distributing chamber throughout the upper portion of said inlet opening, a horizontal partition within said casing spaced from the forward end thereof and with 5 its rear end extending into the distributing chamber and abutting the rear, wall thereof, whereby the combustion gases enter said casing at the rear, pass forwardly therein beneath the baffle, then upwardly and thence rearwardly over the baffle into the lower portion of the distributing chamber.

2. In a furnace, a grate, a combustion chamber above the grate, a horizontal fire tube boiler having the inlet ends of the tubes communicating with the upper rear portion of the combustion chamber, means enclosing the inlet ends of the tubes and forming a distributing chamber, said means having an elongated inlet opening at its lower forward end .co-extensive with the width of the boiler, a flattened elongated casing constituting a heating chamber extending forwardly parallel to the grate from said distributing casing being closed at its forward end and communicating at its rear end 05 with said distributing chamber throughout the upper portion of said inlet opening, a horizontal partition within said casing spaced from the forward end thereof and with its rear end extending into the distributing chamber and abutting the outer ends of said fins being provided with transversely registering clean-out openings, there being a passageway leading from the exterior of the furnace into said heating chamber in registration with said clean-out openings, and a removable plug for the last mentioned passageway.
